Civil aviation passenger plane high-precision positioning method based on multiple sensors, equipment and medium

Abstract

The invention provides a civil aviation passenger plane high-precision positioning method based on multiple sensors. The civil aviation passenger plane high-precision positioning method comprises thesteps of calculating flight correction GPS height, calculating flight correction radio height, calculating flight correction inertial navigation height and calculating flight optimal height data. Theinvention relates to electronic equipment and a storage medium, which are used for executing the method. Compared with an existing passenger plane high-precision positioning technology, equipment nodes and infrastructures do not need to be additionally configured, universality is high, and high-precision positioning requirements in most flight scenes can be met; compared with traditional airborneGPS positioning, the positioning accuracy is greatly improved, and a firmer guarantee is provided for flight safety of a passenger plane; high-precision positioning can be realized only by acquiring asmall amount of earlier-stage empirical data, so that the method has good practicability and expandability; the high-precision positioning data provided by the invention provides more real flight passenger plane basic position data for academic research in many fields of the civil aviation industry.

Description

technical field [0001] The invention relates to the technical field of spatial positioning and navigation of aircraft, in particular to a multi-sensor-based high-precision positioning method, equipment and medium for civil aviation passenger aircraft. Background technique [0002] With the rapid development of the civil aviation industry, positioning has become one of the important modules in civil aviation passenger aircraft. Satellite navigation and positioning systems such as GPS and Beidou have become the most important modules for current civil aviation passenger aircraft because of their advantages such as all-weather, high precision, wide coverage, and strong real-time performance. The mainstream way of its own position. [0003] However, satellite navigation and positioning systems such as GPS and Beidou also have many shortcomings that are difficult to overcome. For example, problems such as refraction of satellite signals in the atmosphere, satellite clock synchro...

Problems solved by technology

However, technologies such as SBAS, GBAS, and DGPS often require the deployment of specialized equipment nodes and infrastructure, and their current popularity is far from reaching global coverage. Once civil aviation airliners lose the support of new technologies, the positioning accuracy will return to At the origin, research that relies heavily on high-precision positioning, such as instrument landing system signal quality analysis with the help of airborne data, will be greatly challenged or even stagnated
